TS32MLD72V6F5
Placement
Description
The TS32MLD72V6F5 is a 32Mx72bits Double Data Rate
SDRAM high-density for DDR266. The TS32MLD72V6F5
consists of 9pcs CMOS 32Mx8 bits Double Data Rate
SDRAMs in 66 pin TSOP-II 400mil packages and a 2048
bits serial EEPROM on a 184-pin printed circuit board.
The TS32MLD72V6F5 is a Dual In-Line Memory Module
and is intended for mounting into 184-pin edge connector
A
sockets.
Synchronous design allows precise cycle control with the
use of system clock. Data I/O transactions are possible
B
on both edges of DQS. Range of operation frequencies,
programmable latencies allow the same device to be
useful for a variety of high bandwidth, high performance
C
memory system applications.

Note: 1. Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise
and DC offset on VREF, bandwidth limited to 20MHz. The DRAM must accommodate DRAM current
spikes on VREF and internal DRAM noise coupled. TO VREF, both of which may result in VREF noise.
VREF should be de-coupled with an inductance of <=3nH.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is
expected to be set equal to VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on /CK.
4. These parameters should be tested at the pin on actual components and may be checked at either the
pin or the pad in simulation. The AC and DC input specifications are relation to a VREF envelop that has
been bandwidth limited to 200MHZ.
5. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in
the dc level of the same.

Note: 1. Maximum burst refresh of 8
2. The specific requirement is that DQS be valid(High or Low) on or before this CK edge. The case shown
(DQS going from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a
previous write was in progress, DQS could be High at this time, depending on tDQSS.
3. The Maximum limit for this parameter is not a device limit. The device will operate with a great value for
this parameter, but system performance (bus turnaround) will degrade accordingly.

OP Code: Operand Code. A0 ~ A12 & BA0 ~ BA1: Program keys. (@EMRS/MRS)
EMRS/ MRS can be issued only at all banks precharge state. A new command can be issued 2 clock cycles after EMRS or MRS.
Auto refresh functions are same as the CBR refresh of DRAM. The automatically precharge without row precharge command is meant
by "Auto". Auto/self refresh can be issued only at all banks precharge state.
BA0 ~ BA1: Bank select addresses. If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If
both BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected. If both BA0 is "Low" and BA1 is
"High" at read, write, row active and precharge, bank C is selected. If both BA0 and BA1 are "High" at read, write, row active and
precharge, bank D is selected.
If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected.
During burst write with auto precharge, new read/write command cannot be issued. Another bank read/write command can be issued
after the end of burst.
Burst stop command is valid at every burst length.
DM sampled at the rising and falling edges of the DQS and Data-in is masked at the both edges (Write DM latency is 0).
This combination is not defined for any function, which means "No Operation (NOP)" in DDR SDRAM.
